[It is well known that special means are frequently necessary to impart an increased mechanical strength to human hair particularly if the hair inherently is too soft and of too lose a texture to form it into a somewhat permanent or longer lasting hair style. This type of hair is frequently also quite sensitive towards exterior action such as wind or strong agitation which cause the hair style to be ruined after only a short period of time.

To overcome these shortcomings there are used particularly high polymeric compounds which are adapted to form a deposit on the surface of the hair in the form of a coherent film and therefore have a stiffening effect and increases the mechanical strength of the hair. To some extent hair thus treated is better adapted to be shaped and retain the shape for a longer period of time.

High molecular weight polymers for this purpose are numerous polymers of different composition such as for instance natural polymers like tragacanth, agar agar, quince mucila-ge, pectin and karaya. Likewise synthetic polymers are used for this purpose, for instance vinyl polymers such as polyvinylpyrrolidone, polyvinylacetate or polyacrylate compounds such as acrylate acid polymers, methacrylic acid polymers, basic polymers of esters formed from both of these acids with amino alcohols or the salts or quaternary reaction products thereof, polyacrylonitrile, and corresponding copolymers from these compounds as for instance a vinylpyrrolidone-vinylacetate copolymer.

These conventional compounds for stiffening and setting the hair are however not entirely adequate since there is a desire to obtain still better shapeability of the hair and improved retention of the shape. This applies particularly also to shampoos and hair conditioners which usually do not contain this type of polymeric compounds and are usually removed from the hair after a limited period of action. Following treatment with these compounds the hair however should also be adapted to be shaped easily and to retain a shape thus imparted.

SUMMARY OF THE INVENTION The present invention resides in the addition to treating compositions containing setting agents, shampoos or hair conditioning agents and possibly also a dyeing or shading agent, of about 0.2 to 6% of finely divided silicon dioxide or aluminum oxide.

DETAILED DESCRIPTION OF THE INVENTION AND OF PREFERRED EMBODIMENTS The silicon dioxide is preferably used in the form of the commercial product which is sold by the Degussa Company of Frankfurt, Germany, under the trademark Aerosil or under the trademark Cab-O-Sil by the Cabot Corporation of Boston. The particle size of these oxides is generally in the average range of about 2 to 40 Inn.

The aluminum oxide (A1 0 is preferably used as the product sold under the name Alon by the Cabot Corporation of Boston and usually has a similar particle size for instance of about 30 m For compositions containing hair setting agents the finely dispersed oxides preferably are used in a concentration between 0.2 and 0.7% by weight of the total composition. The polymers in these hair setting lotions may be any of the conventional type of which above a few examples have been given. The concentration of the setting agent is usually between 1 and 4% by weight in an aqueous-alcoholic solution.

These compositions are usually applied to the hair after it has been subjected to a prior shampoo and the treatment is then followed by setting and drying the hair.

The setting agents, it will be understood, may also contain dyeing agents for shading the hair. These so-called shading or dyeing setting agents are well known and commercially available. The dyes should be those which are applied directly to the hair and preferably in a concentration between about 0.01 and 0.5% by weight of the total composition. The following dye groups may be mentioned by way of example:

Aromatic nitro dyes such as 4-nitro-1,2-diaminobenzene and 2-nitro-1,4-diaminobenzene Triphenylmethane dyes such as methylvioiet B Azo dyes Anthraquinone dyes such as the Cellitone compounds of the Badische Anilin und Soda Fabrik of Germany.

The dyes of these various groups may either have an acid or a basic character depending on the particular constituents which are present.

The finely divided submicroscopic oxides preferably are used in the same proportion as in the above hair setting agents which do not contain dyes.

In the washing agents (shampoos) the component having the washing action may be the conventional anionic, cationic or nonionic or amphoteric compounds in the conventional concentration of about 10 to 30% by weight of the total composition.

There are mentioned here as examples of anion active compounds the alkylsulfonates, alkylarylsulfonates, alkylsulfates, fatty acid condensation products, sulfonesuccinic acid esters and albumin condensation products. Among the cation active substances there may for instance be used salts of higher molecular amines or quaternary ammonium compounds. Examples of non-ionic compounds are for instance the polyglycol ethers of fatty alcohols or alkyl phenols and fatty acid alkyl amides. The amphoteric compounds may be exemplified by the betaines having carboxylic acid or sulfonic acid groups.

These agents are used in conventional manner and preferably in a thin liquid or in a composition of higher viscosity. In this case the proportion of finely divided silicon dioxide or aluminum III-oxide is preferably between 0.5 and 6% by weight of the total composition.

The hair treating compositions of the invention may contain the conventional materials for conditioning the hair, such as, fatty alcohols, fatty acid esters, lanolin derivatives, paraffins, such as Vaseline etc.

The compositions are preferably used in the form of emulsions of varying consistency.

It will be understood that the treating composition may also contain other additives as are customary in the hair dressing cosmetics industry such as preservatives, bactericides, perfume oils, etc.
